Code + ComboBox

[FONT=Times New Roman][SIZE=3]I’ve added a combo box to the stage,[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]In the combo box properties\ Parameters tab, I’ve entered some data.[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]snd_1, snd_2, snd_3, etc[/SIZE][/FONT]
[SIZE=3][FONT=Times New Roman]// myCombo [/FONT][/SIZE]
[SIZE=3][FONT=Times New Roman]var bigEars:Object = new Object();[/FONT][/SIZE]
[SIZE=3][FONT=Times New Roman]myCombo.addEventListener(“change”,bigEars);[/FONT][/SIZE]
[SIZE=3][FONT=Times New Roman]bigEars.change = function() {trace(_root.myCombo.selectedItem.data);}[/FONT][/SIZE]

[FONT=Times New Roman][SIZE=3]Works fine, trace output shows the selected combobox item. snd_1, snd_2, snd_3, etc[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]I’m having trouble using this returned item in a statement.[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]_root.[COLOR=seagreen]snd_ch1[/COLOR].start(0,20); plays a sound[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3]_root.[COLOR=seagreen]myCombo.selectedItem.data[/COLOR].start(0,20); doesn’t play a sound[/SIZE][/FONT]
[FONT=Times New Roman][SIZE=3][/SIZE][/FONT]
Edit
Sorry I should have explained,
In my Library I have a sound file called ch1.WAV
It has Linkage Properties Identifier ch1
I used a bit of code …
var snd_ch1 = new Sound()
snd_ch1.attachSound(“ch1”)
End Edit

[SIZE=3][FONT=Times New Roman]My problem is not so much a combo box problem, it’s more of a code problem.[/FONT][/SIZE]
All help much appreciated
